I found this nice free downloadable Challenger II made for Xplane 10 but which works fine in Xplane11. Has a 3d panel too, although the Challenger panel is fairly simple, being a Light Sport aircraft. The Challenger II can be found here--download version 1.3:

The CFI who signed off on my Light Sport student license owned a Challenger, but sadly lost it after an engine failure. He and his passenger survived shaken but not hurt, but sadly when he landed on Lake Pleasant highway the port wing hit a road marker and crumpled. That said, that is one advantage of a dope and fabric aircraft in a crash, they absorb the impact by crumpling like modern passenger cars and there is less metal to hurt the occupants. I found out about his crash on the news... I called him that evening and he gave me the details of the crash, this is a report of the incident:
